Keeper Secret Manager Security and Encryption Model
Keeper Secrets Manager is a Zero Knowledge platform. Encryption and decryption of secrets takes place locally on the Client Device running the ksm application, CI/CD plugins or the developer SDK.
The local configuration file (e.g. keeper.ini) for the ksm application contains the following format:
This file should be protected on your local filesystem. It contains keys can authenticate with the Keeper API and decrypt secrets that have been explicitly associated with the Application and Client Device.
The Client Device only authenticates with the hashed One Time Access Token one time. The client signs the payload and registers a Client Device Public Key with the server on the first authentication. After the first authentication, subsequent requests are signed with the Client Device Private Key.
API requests to the Keeper Cloud are sent with a Client Device Identifier and a request body that is signed with the Client Device Private Key. The server checks the ECDSA signature of the request for the given Client Device Identifier using the Client Public Key of the device.
The Client Device decrypts the ciphertext response from the server with the Application Private Key, which decrypts the Record Keys and Shared Folder Keys. The Shared Folder Keys decrypt the Record Keys, and the Record Keys decrypt the individual Record secrets.
By default, when creating a Client Device profile, IP lockdown is enabled.
For example:
The client which initializes using this token will be locked on IP. To disable IP lockdown, an additional parameter must be specified, for example:
It is recommended to allow IP lockdown, unless you are deploying to an environment which has a dynamic WAN IP.
